Rest - 响应中的 MediaType 与请求中的相同

Question

I have a web service that consumes XML and JSON .
The output is currently always in XML .
Is it possible to produce the response in the same MediaType as the MediaType that was consumed?

What i need is:
The request is XML , the response is XML too.
The request is JSON , the response is JSON too.

My Code:

@Path("/calculate")
public class CalculationService
{
    @POST
    @Path("/magic")
    @Consumes({ MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON })
    @Produces({ MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON })
    public Output calculate(Input input)
    {
        Output output = new Output();
        output.setValue1(...);
        output.setValue2(...);
        output.setValue3(...);

        return output;
    }
}

By default, the Web service delivers the response as MediaType.APPLICATION_XML .

The MediaType can be controlled by setting the Accept-Header .

By setting the value Accept: application/json , the response is delivered as MediaType.APPLICATION_JSON .
